A three-dimensional particle image velocimetry method is described, in which a stream system containing light-scattering particles is exposed continuously over a certain period or at least two discrete points in time using a laser lightsheet, and a hologram is produced and evaluated. Increased accuracy in determining velocity is achieved by evaluating the hologram with regard to its phase information interferometrically by using a reconstruction wave and superimposing a reference wave.
